/**
* The nsIDOMSimpleGestureEvent interface is the datatype for all
* Mozilla-specific simple gesture events in the Document Object Model.
*
* The following events are generated:
*
* MozSwipeGesture - Generated when the user completes a swipe across
* across the input device.
*
* MozMagnifyGestureStart - Generated when the user begins the magnify
* ("pinch") gesture. The "delta" value represents the initial
* movement.
*
* MozMagnifyGestureUpdate - Generated periodically while the user is
* continuing the magnify ("pinch") gesture. The "delta" value
* represents the movement since the last MozMagnifyGestureStart or
* MozMagnifyGestureUpdate event.
*
* MozMagnifyGesture - Generated when the user has completed the
* magnify ("pinch") gesture. If you only want to receive a single
* event when the magnify gesture is complete, you only need to hook
* this event and can safely ignore the MozMagnifyGestureStart and the
* MozMagnifyGestureUpdate events. The "delta" value is the cumulative
* amount represented by the user's gesture.
*
* MozRotateGestureStart - Generated when the user begins the rotation
* gesture. The "delta" value represents the initial rotation.
*
* MozRotateGestureUpdate - Generated periodically while the user is
* continuing the rotation gesture. The "delta" value represents the
* rotation since the last MozRotateGestureStart or
* MozRotateGestureUpdate event.
*
* MozRotateGesture - Generated when the user has completed the
* rotation gesture. If you only want to receive a single event when
* the rotation gesture is complete, you only need to hook this event
* and can safely ignore the MozRotateGestureStart and the
* MozRotateGestureUpdate events. The "delta" value is the cumulative
* amount of rotation represented by the user's gesture.
*
* MozTapGesture - Generated when the user executes a two finger
* tap gesture on the input device. Client coordinates contain the
* center point of the tap.
* (XXX Not implemented on Mac)
*
* MozPressTapGesture - Generated when the user executes a press
* and tap two finger gesture (first finger down, second finger down,
* second finger up, first finger up) on the input device.
* Client coordinates contain the center pivot point of the action.
* (XXX Not implemented on Mac)
*
* Default behavior:
*
* Some operating systems support default behaviors for gesture events
* when they are not handled by the application. Consumers should
* use event.preventDefault() to prevent default behavior when
* consuming events.
